Anti-Gravity Mirror
Here’s an exhibit where watching is at least half the fun. You can create any number of gravity-defying illusions that will amaze you and your friends: Levitate, fly, swim though the air, grow limbs (and dissolve them), crawl straight up the wall like a lizard—the sky’s the limit.
Benham's Disk
When the disk is spun, the colors you see are illusions. This effect was popularized in 1894 by toymaker C. E. Benham, who called his spinning disk an “artificial spectrum top."
Big Chair, Little Chair
Each of the chairs in this series has dimensions that are twice that of the smaller chair. But doubling the dimension of a chair doesn’t double its strength.

Giant Mirror
This giant mirror was originally part of a flight simulator. Its size and near-perfect smoothness makes for astonishing optical (and acoustic) effects.
Gray Step
With the rope hanging down, the left and right sides of the board appear identical. Lifting the rope shows the dramatic difference that your eyes missed—and continue to miss, as soon as you let the rope fall again.
